Field studies were carried out to determine the effect of rate and frequency of fertilization, primarily nitrogen, on the total production of forage and crude protein of Pensacola Bahiagrass and Pangolagrass under central Florida conditions, and to estimate their persistence under conditions of high fertility.
The optimum nitrogen fertilization rate for Bahiagrass over the 5-year period was 240 pounds per acre applied in 2 applications per year. Bahiagrass was damaged by single applications of greater than 240 pounds of nitrogen. The data showed that 200 pounds each of P2O5 and K2O represented more than adequate levels of these nutrients. There was no benefit from split application of phosphorus and potassium, which were applied at 200 pounds (oxide basis) per year.
Pangolagrass responded to higher levels of nitrogen application—the optimum level was 320 pounds of nitrogen per acre per year. This grass can tolerate single applications of nitrogen up to 480 pounds per acre. In terms of forage or protein production, there was no advantage in split applications of nitrogen.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
